For a while now, VR Tuned has offered ECU tuning for all F-Series BMW vehicles. This includes the new F30 BMW 335I and the F32 435I with the N55 turbo engine. These inline 6-cylinder engines hold a lot of room for improvement in terms of horsepower and torque. Note that an aftermarket catless downpipe and catback will surely help the turbocharger breathe better, giving the car’s already-tuned ECU even more gains. In addition, higher octane such as 93 or 95 gas will yield more horsepower for your vehicle too.
The BMW 335I N54 really changed the BMW market as the first turbocharged tuner platform. The twin-turbo 6-cylinder engine demonstrates excellent power throughout the entire curve. As with any tuner platform, the mods are essentially endless. One of the basic modifications you can do to the 335I N54 is an ECU tune. To flash these ECUs, the ECU must be removed from the car completely. All of our ECU flashes for the 335I N54 and N55 are done via the OBDII port. We here at Vivid Racing do basic map changes to improve horsepower and torque. This tune will take your car from 302HP | 295ft/lbs to 370HP | 369ft/lbs. We have customers around the world that run our tuning systems in different climates, environments, octanes and competition.
